Description

A kind of energy-saving exhaust pipe featuring of changeable pressure

Technical field

The utility model relates to a kind of energy-saving exhaust pipe featuring that is installed in the changeable pressure with exhaust gas recirculation function on the engine exhaust pipe.

Background technique

The exhaust pressure that present available engine is produced when work is different variation of rotating speed operating mode with motor, because the exhaust diameter of traditional automobile exhaust pipe is unalterable, so just cause the air pressure of motor outlet pipe when low-load is worked not enough, mixed gas just can not absorb the after-heat of staying cylinder waste gas after entering cylinder like this, cause fuel to can not get fully volatilization vaporization, make mixed gas can not get sufficient burning, and insufficient carbon on engine and the operating temperature height of also can causing of mixture combustion influences the problems such as working life of motor.The too high engine exhaust that can cause again of air pressure in the outlet pipe is not smooth when high engine load is worked conversely, deficiency of air, mixed gas overrich, the resistance of motion strengthens, and the vibrations of motor are big, and oil film is inhomogeneous, engine operating temperature raises, carbon distribution, shortcoming.So the motor of automobile is the outlet pipe that needs an energy transformation (slow-speed of revolution pressurize high rotating speed decompression) in actual use.

Embodiment

With reference to Fig. 1, Fig. 2, a kind of energy-saving exhaust pipe featuring of changeable pressure, comprise sleeve pipe 1, described sleeve pipe 1 front end and anterior sidewall are respectively equipped with suction port 2 and relief opening 3, be respectively equipped with cover plate 4 and catch 5 in sleeve pipe 1 rear end and relief opening 3 edges, they make and form sealed cavity in the sleeve pipe 1, the sealed cavity internal fixation that is positioned at sleeve pipe 1 rear portion has fitting seat sheet 6, there is piston rod 7 to pass cover plate 4, fitting seat sheet 6 and catch 5, described piston rod 7 front ends are provided with piston sheet 8, these piston rod 7 outer walls are positioned at the sealed cavity part and also are with the support sheet 9 that adapts with the sealed cavity size, have spilehole 10 on the described support sheet 9, described piston rod 7 outer walls are set with spring 12 between support sheet 9 and fitting seat sheet 6, have the bolt 16 of adjustment to be arranged at piston rod 7 rear ends, and described piston rod 7 outer walls are positioned at adjustment bolt 16 front ends and are provided with damping spring 18.

The waste gas of being discharged when motor acting is when suction port 2 is stamped on the piston sheet 8, waste gas is discharged from relief opening 3, the elastic reset that piston sheet 8, piston rod 7 are subjected to exhaust gas pressure extruding and spring 12 seesaws in sleeve pipe 1, so just can change the outlet pipe pressure inside automatically, to keep in the cylinder suitable air pressure being arranged, improve the burning of motor, reduce fuel consume.This device makes the part waste gas after the burning push back the effect that cylinder plays exhaust gas recirculation from exhaust valve; And apparatus structure of the present utility model is simple, with low cost, need not control system control, can on all waste pipes, install, and long service life, can reach energy-conserving and environment-protective easy to install and use advantage and improve power-lift power and reduce exhaust noise and the purpose of mechanicalness noise.

In the utility model, between support sheet 9 back and spring 12, be with magnet I 11 on the described piston rod 7, be fixed with the small casing 13 that is enclosed in outside the piston rod 7 on the described fitting seat sheet 6, described small casing 13 outer walls are provided with the magnet II 14 that attracts mutually with magnet I 11.

Because attracting each other, magnet I can change the pressure that the piston sheet is opened automatically near magnet II the time, outlet pipe exhaust pressure when the high rotating speed high load of motor is diminished, make exhaust resistance reduce to reach and increase engine horsepower, when low speed, increase the exhaust pressure of motor, increase the low speed torque of motor, reduce fuel consume.Can make the part waste gas after the burning push back the effect that cylinder plays exhaust gas recirculation by said process from exhaust valve.

This product situation that the outlet pipe exhaust diameter can not change that breaks traditions, it is the venting gas appliance that can change the exhaust pressure of automobile exhaust pipe by variable valve. unique slow-speed of revolution pressurization and high rotating speed decompression technology make the low engine speed moment of torsion installed behind this outlet pipe and at a high speed horsepower obviously promoted. the powerful 0-100 of automobile acceleration performance quickens compared with not having before the dress not fast more than 2 seconds. and not sacrifice oil consumption in power-lift be cost, thereby owing to can make the exhaust pressure of motor remain on the optimum state the heat of the fuel absorption waste gas that enters cylinder is fully volatilized on the contrary, mixed gas is just burnt more fully like this, so the motor that this outlet pipe is installed can both keep the state of maximum energy-saving at any rotating speed state, energy-saving effect reaches more than 20%. and for example one 1.6 motor is installed match in excellence or beauty 2.0 motor of its kinetic force behind this outlet pipe, but oil consumption but is equivalent to a motor below 1.3. this outlet pipe has also reduced the operating temperature of motor simultaneously when improving burning, reduce the formation of carbon on engine, the vibrations that reduce motor make lubricant film more even, and the internal friction that reduces motor prolongs the working life of motor. and (experimental results show that motor in driving 5000 change 6000 and all do not feel vibrations more than changeing).

With reference to Fig. 3, Fig. 4, the difference of this structure and Fig. 1, Fig. 2 is magnet II 14 is replaced to coil 15, change the exhaust pressure of outlet pipe by size to the direction of the electrical current of coil 15 and electric current, can play and first kind of effect that mode of execution is identical, maybe can the pressure of exhaust accurately be controlled by the current direction of car running computer ECU control energising and the size of electric current.To reach purpose energy-conservation and lifting power.

In the utility model, small casing 13 outer walls are positioned at magnet II 14 or coil 15 rear ends are provided with Regulation spring 17; Can regulating magnet II 14 or the position of coil 15 by Regulation spring 17, can further accurately control like this exhaust pressure, make energy-saving effect and promote the engine power effect to reach best.

In the utility model, be positioned at fitting seat sheet 6 rear ends on the sleeve pipe 1 and be provided with location jump ring 20, by fitting seat sheet 6 well being fixed under the effect of location jump ring 20 and spring 12.

In the utility model, described piston rod 7 is provided with bulge loop 21, is the boundary with bulge loop 21, and its bar directly is pre-small post-large.Because the gas of discharging from motor has bigger heat, in order to reduce the transmission of heat of piston rod 7, do not allow sleeve pipe 1 inner sealing cavity temperature too high, guarantee the working life of product, piston rod 7 bars in support sheet 9 the place aheads directly can be done littler its transmission of heat that reduces; And bar footpath in rear end is greatly to make and obtain higher supporting force for convenience.

In the utility model, scribble lubricating grease in the described sealed cavity to protect inner friction parts, play lubrication.

The utility model is simple in structure, with low cost, need not control system control, and long service life, can reach easy for installation and the environmental protection advantage, can also play and improve power, and hoisting power also reduces exhaust noise and the purpose of mechanicalness noise.
